I bought a bottle of Sally Hansen Hard as Nails clear nail polish after I read about it on the Internet. Someone was praising this product for how well it strengthens nails and helps to stop breaking and chipping. My nails used to break once in a while, ruining my manicure efforts, so I decided to try this nail polish. I chose the clear version, although there were also many other colors available.
At first, this nail polish seemed to be no different from any other: I had applied two coats and wore it for about a week; then it had began peeling off. However, after several weeks of using it I had noticed that my nails became harder and would not break so often as before when I grew them longer. Since then, I have always kept a bottle of this nail polish around, treating my nails with it once in a while. My nails hardly ever break anymore.
